摘要
本文采用现场时间分辨光谱电化学技术结合循环伏安电化学方法对胆绿素(BV)在纯二甲基甲酰胺(DMF)和DMF-H_2O混合溶剂中的电化学氧化反应进行了较为系统的研究,并提出了相应的反应机理.实验中发现,在有机溶剂DMF中引入水不但促进了BV氧化反应的进行,而且还使BV的氧化反应由在DMF中的ECEC历程转变为ECCECC反应过程.
A systematic study has been made for the electrochemical oxidation reaction of biliverdin (BV) in pure dimethylformamide (DMF) and in DMF - H2O mixed solvent by in situ time resolved spectroelectrochemical and cyclic voltametric techniques. The experiments show that not only the oxidation of BV is promoted, the reaction mechanism is also changed from a ECEC to a ECCECC process by the introduction of water into DMF.
